Can you confirm that this points to the correct place? what does
list.files("C:\\Progra~1\\Graphviz2.20\\bin")
display?

this is the Windows short name of the file. In a DOS shell try
DIR/x "c:\Program Files\R"
to see. Nothing to be concerned about.

Was file1eb260 in the c:\Program Files\R\R-2.9.1\library directory? If
so, remove it. Also remove the version that you renamed as Rgraphviz,
and you might as well remove Rgraphiz-broken while you're at it. Do
this
using Windows; no need to involve R. Likely these are left-overs from
a
failed installation attempt.

With your cleaned up R, and with your PATH variable set correctly.
What
happens when you ask to install Rgraphviz using biocLite
source('http://bioconductor.org/biocLite.R')
biocLite('Rgraphviz')
?
